That’s a $30,000 rig at least. So 300 days of mining before you just break even. I’m sure that in 300 days it will only be able to mine a fraction of what it does now due to increasing difficulty. I’m not seeing how this truly works out.
Coincidentally my GPUs have not only paid for themselves and then some, but I could sell them used now for more than I bought them for. I’m lucky in that respect.
